Got a cutting from my Biology teacher. Let's see how it does...

This species sometimes falls apart if underwatered, its what experts call a 'drought deciduous' plant meaning if it isn't getting enough water it will start to shed pads to conserve what water it does get. This often baffles the person growing it as it appears to be falling to bits for no apparent reason.

I bought a pad from Rio Grande Cactus who says its hardy in zone 7. We shall see. So far its coming along faster than most cuttings.

This cactus has a very pleasing growth habit and its pads reminded one of Dave's Garden member of dotted swiss material. Its medium green color nicely sets off the white "dots". Placed in front of other cacti and succulents or just as a solitary planting, it is a great accent plant especially when in bloom.
